Bot GPT 4-o mini To calculate \( (4.8 \times 10^{-3}) - (9.4 \times 10^{-6}) \), we first need to express both numbers in the same power of ten.
The first term is \( 4.8 \times 10^{-3} \). We can express \( 9.4 \times 10^{-6} \) in terms of \( 10^{-3} \) to make the subtraction easier:
\[ 9.4 \times 10^{-6} = 0.0094 \times 10^{-3} \]
Now we can rewrite \( 9.4 \times 10^{-6} \): \[ 9.4 \times 10^{-6} = 0.0094 \times 10^{-3} \]
Now we can perform the subtraction: \[ (4.8 \times 10^{-3}) - (0.0094 \times 10^{-3}) = (4.8 - 0.0094) \times 10^{-3} \]
Calculating \( 4.8 - 0.0094 \): \[ 4.8 - 0.0094 = 4.7906 \]
So we have: \[ (4.7906) \times 10^{-3} \]
Now, we need to express this in scientific notation and round to 2 decimal places: \[ 4.7906 \times 10^{-3} \approx 4.79 \times 10^{-3} \]
Thus, the final answer is: \[ \boxed{4.79 \times 10^{-3}} \]
